When we build our images we attempt to checkout all of the valid devstack branches so that we can list all of the images necessary to be cached for each branch. Unfortunately this devstack repo is owned by root during dib and snapshot image builds. This means we must use sudo when updating the repo (either changing branches or updating the current branch).
